This American Thunder® exhaust system comes as a complete true dual headers-back exhaust for your 1969 Chevrolet Camaro or Pontiac Firebird with V8 engine. These dual systems feature 2.50 in. mandrel-bent aluminized steel tubing for maximum performance, includes a built-in H-pipe/balance tube flowing into a pair of Super 44® mufflers that deliver a moderate to aggressive interior and exterior tone and are suited to the enthusiast who wants their performance to be heard. The 2.50 in. tailpipes exit straight out under the rear bumper and are finished off with 2.50 in. angle-cut brushed stainless steel tips and includes all hangers and necessary hardware for installation. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage. Covered by our 3-year Limited Warranty.
